Do you own a 2014-2018 GM Tahoe, Yukon, Suburban, Silverado, or Sierra with a 6L80/90E or 8L90 transmission? Are you aware of the thermostat in your transmission cooler lines that remains closed until fluid temperatures approach almost 200 degrees? This thermostat can cause transmission and torque converter failures in numerous 2014-2018 GM vehicles. As the fluid temperature rises, the transmission torque converter and clutch packs become overheated causing premature wear and failures. We are proud to offer a simple thermostat bypass solution utilizing Shift Technology Product's Bypass kit. Contact us today to schedule this upgrade and prevent potential transmission problems.
